Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of broadcast information transmission method based on satellite mobile communication system and equipment.
Background technology
For utilizing the land mobile communication system, can utilize LTE(Long Term Evolution, Long Term Evolution) system/LTE-A(LTE-Advanced, senior LTE) system disposes satellite mobile communication system, and it comprises the satellite mobile communication system of tupe on the satellite mobile communication system of transparent forwarding pattern and the star; As shown in Figure 1, in the satellite mobile communication system of transparent forwarding pattern, inserting of satellite point device (such as eNodeB) is deployed in ground, transparent forwarding was to the inserting of satellite point device after the data communication device of ICBM SHF satellite terminal was crossed satellite reception; With shown in Figure 2, on star, in the satellite mobile communication system of tupe, the inserting of satellite point device is deployed in above the satellite, is connected by eating dishes without rice or wine between inserting of satellite point device and the ICBM SHF satellite terminal, and communicate by letter with the ground gateway station via satellite, communicated by ground gateway station and core net.
As shown in Figure 3, in satellite mobile communication system, the multichannel feed of going up via satellite (common tens even up to a hundred) and satellite antenna can form the space narrow beam by the figuration network at satellite, and each wave beam are equivalent to a residential quarter; Because satellite is far to the propagation distance on ground, so the wave beam design concept of satellite mobile communication system is: 1) improve beam forming gain, form gain up to the overall gain of 40-50dBi by a plurality of feeds and antenna as far as possible; 2) single beam angle is narrower, as shown in Figure 4, take the GEO(geosynchronous satellite) be example, in order to improve the satellite system capacity, the coverage distance of single wave beam on ground requires in 400-500Km, and apart from 36000Km, then the broadband of single wave beam is usually about 0.6 degree according to satellite orbit; 3) beam center and edges cover level are as far as possible balanced.
As shown in Figure 5, because coverage distance is far in the satellite mobile communication system, descending and upper provisional capital shows as stronger power limited characteristic; On down link, need satellite to send guarantee ground with very large power and receive, but the power on the satellite is often limited; On up link, because the ICBM SHF satellite terminal power limited then requires satellite receiver to have very high sensitivity usually; Based on this, require the wave beam of satellite communication as far as possible identical at the covering level at center of housing estate and edge.
Based on above-mentioned characteristic, in order to improve the coverage strength of satellite-signal, it is as far as possible identical to require ground to cover level in the satellite mobile communication system, and signal intensity difference is very little between center of housing estate and the cell edge; Based on this, if identical networking is adopted in each residential quarter, then can there be stronger interference in the minizone of satellite mobile communication system overlapping very serious between the residential quarter, and namely co-channel interference will be very serious; Therefore in order to guarantee communication quality, satellite mobile communication system generally adopts the inter-frequency networking mode, as shown in Figure 6, typical frequency multiplexing mode such as common cellular system, its frequency reuse system is 7.
In the prior art, in order to make the terminal can very fast search cell, obtain the basic configuration of residential quarter, in the LTE/LTE-A system, designed PBCH(Physical broadcast channel, Physical Broadcast Channel), be used for carrying MIB(Master Information Block, Master Information Block) information, and comprise following content in the mib information: the downlink bandwidth indication, PHICH(Physical HARQ Indication Channel, the physical mixed automatic re-transmission indicating channel) configuration information (being used for supporting PHICH channel and relevant information), System Frame Number (being used for the terminal downlink frame synchronization) etc.

Embodiment
Below in conjunction with the accompanying drawing among the present invention, the technical scheme among the present invention is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Embodiment one
The embodiment of the invention one provides a kind of broadcast information transmission method based on satellite mobile communication system, this satellite mobile communication system can be disposed based on LTE system/LTE-A system, and the method can be applied in the satellite mobile communication system of tupe on the satellite mobile communication system of transparent forwarding pattern or the star, as shown in Figure 7, the method may further comprise the steps:
It should be noted that, for satellite mobile communication system, because the distance of spatial is far, time delay is very large, therefore wish to dispose as early as possible suitable Timing Advance, with dropping in the time of reception window as early as possible, be that ICBM SHF satellite terminal is very obvious to the locational requirement of satellite in the space, and can not carry the absolute time value information of satellite orbital position information and/or present frame in the mib information of existing LTE system/LTE-A system, the sending method of therefore existing mib information also is not suitable for satellite mobile communication system; Based on this, in the embodiment of the invention, in broadcast message, need to carry at least the absolute time value information of satellite orbital position information and/or present frame.
Further, ICBM SHF satellite terminal is after receiving the absolute time value information of satellite orbital position information and/or present frame, can utilize the absolute time value information of satellite orbital position information and/or present frame, determine the particular geographic location of satellite, thereby can calculate Timing Advance based on the positional information of self and the particular geographic location of satellite, and send coherent signal to satellite faster based on this Timing Advance.
